Use second router behind Sky hub

[ape72]

I have a Sky hub (SR203) but I don't like the interface and it's not as flexible as my own router (TP Link Archer C9). I would like the internet traffic to continue to come through the Sky Hub but my own router does everything else (see diagram).

On my Sky Hub I assume I have to make changed to these 2 screens (see below).

@ape72 you can add your router behind the Sky hub but there is no requirement to change the WAN or LAN IP set up screen as you cannot stop the Sky hub acting as a router. I would turn off the Sky hub's wifi and if you want to you can place the TP-Link in the Sky hub's DMZ to disable its firewall. 

You will inevitably have a double Network Address Translation set up which doesnt stop most apps from working but a few may not like.

Thanks for the quick response. Much appreciated. If I want to use port forwarding on my TP Link router instead of the Sky hub, do I need to do anything funky? I'm hoping I can have the Sky Hub as 192.168.0.1, the TP Link as 192.168.0.2 and have DHCP and port forwarding on the TP Link.

Is this revised network setup correct?

You cant have DHCP & Port forwarding on your TP-Link router if your going to keep your Sky hub on 192.168.0.1

The Sky hub will not act as a DHCP client so it either must be the DHCP server or it needs to have DHCP disabled & your TP-Link router needs to be on a different IP space.

Thanks for responding. What do you mean by 'different space'?

Sorry I mean as in a different IP address range e.g. Sky hub on 192.168.0.XXX & TP-Link on 192.168.1.XXX
